Firstly Congrats! I really liked this game, and played more than 20-30 + minutes I guess. Here is my 2 cents on the design and game feel.
I think in this prototype the feeling of the ship is a bit drifting. I either want to go faster and have more control over the ship or just be really careful not to hit something and takes things really slowly. I feel constantly trying to be slow (cause the fuel is just draining really quickly even without the boost) and move really carefully is not fun. Then you either strategize really quick and short intervals of extraction or you go really slowly (reverse driving doesnt take fuel so game actually encourages this) and earn a lot of scrap in one run. If the game meant to be an incremental game with adding fuel upgrades in the early stages maybe that wouldn't feel like this. I also felt opening up the menu and redeploy taking some time and that makes the quick-short extraction feel less good. Currently hitting the rocks may not damage you, but it takes your whole velocity immediately and this makes the control of the ship not fun. I rather want taking some damage but going through the meteors with loss on my velocity, at least it's not 0 immediately :) And there'd be shield and other upgrades focusing on this as well?
And oh the rockets, rockets are so fun :) If there were upgrades to make more money earlier I would definitely do it to get rockets faster. I stopped after playing with rockets cause I may give the game another run later. I recently played Astro Prospector which had a similar theme and really good game feel so I'd suggest looking at if you've not done so.
And come on! The sicko graphics mode should be the default, the optional one should be to disabling :)
